We’ve seen the amazing The Mortal Instruments: City of Bones trailer, but the studio behind the sure-to-be blockbuster has never shown us the world they’re making of Cassandra Clare’s bestselling book series like in this new clip.

The featurette showcases the cast and filmmakers talking about the movie, as well as a behind-the-scenes look at the making of the epic fantasy tale. The cast, including Lily Collins (Clary Fray), Jamie Campbell Bower (Jace Wayland) and Jonathan Rhys Meyers (Valentine Morgenstern) -- who says the film is about “mortality and immortality” -- all take us inside the magical world of Clare.

Lena Headey is Jocelyn Fray, Clary’s mother, who tries as long as she can to shield her daughter from her destiny. “She wants to keep her safe,” Headey says in the featurette.
